Aguilar Física, Astronomía y Matemáticas METHODS: N MISCELLANEOUS BODY SIMULATIONS METHODS: MISCELLANEOUS We present a Beowulf type computer built using off-the-shelf hardware andfreely available software. Its performance in raw computational power and parallelefficiency is compared with an SGI Origin-2000 computer using two differentN-body codes. The impact of this technology in opening up the possibility of makingroutine N 106 particle simulations with a home made computer is discussed.The effect of higher numerical resolution is shown with simulations of a cold dissipationlesscollapse and of the vertical heating of the disk component of a spiralgalaxy evolving in isolation. 2003 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57139205 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.2 Vol.39 |
